The main engine of scraper adopts planetary gear transmission. This series of scraper loaders has the characteristics of high rock loading efficiency, simple structure, good reliability, convenient operation and wide application range. Bucket loader is not only used for drift, but also for inclined roadway below 30 degrees. It is the main mechanical equipment to improve the driving speed and realize the mechanization of roadway driving. The scraper loader is equipped with a pneumatic trolley cylinder. After the mine car is fully loaded, the heavy car can be pushed out by the pneumatic pusher cylinder, which reduces the labor intensity of workers, shortens the shunting time and improves the tunneling speed.
